magnets Flashcards
Energy
Motion or interaction of molecules, the ability to do work
electron
Subatomic particle that has a negative charge
magnetism
A force that can attract or repel objects that contain a magnetic material inside them
-caused by electrical charges
-magnetic materials: cobalt, nickel, iron, magnetite
Magnetic field
A region around a magnetic material where the force of magnetism acts
*flow from positive to negative

Protons are positively charged
Electrons are negatively charged
attraction
Being drawn to another object
*Opposite charges attract
Repel
To push away from something
*Same charges repel
Electricity
Energy resulting from charged particles
Static electricity
An imbalance of electric charges within a material
Electric Field
The area around an electric charge that experiences an electric force
*flow from positive to negative
Electric Current
When electric charges move
Open circuit
A path that electricity flows along that is interrupted or disconnected
Closed Circuit
A complete path of electrical connection around which a current flows or circulates
Series circuit
One path through which electricity flows
Parallel Circuit
Multiple paths for electricity to flow from one point to another
